Heat loss calculation

The EASY calculation is performed in 5-10 min.

In order to perform the calculation accurately, we work on the basis of available data such as:

• known consumption
• energy calculation
• surfaces floors

Enter the surface areas and insulation values in a user-friendly manner.

The calculation follows the EN 12831- 1 standard and calculates the required power at building and room level.

Determine the output of underfloor heating (BS EN 1264) and/or select the correct radiator from a database.

Determine the floor finish (stone tiles, wood, ...), the installation distance and automatically calculate the output and temperature of the floor.

Heat-Box also calculates the number of loops needed, the pipe length, the edge insulation, and the flow rates (l/min).

Heat-Box has an extensive radiator database that includes Myson, Jaga, Stelrad, etc.

Select the desired radiator, the flow and return temperature and the correct output power is automatically calculated.
